This paper proposes a practical model for non-Telecom staff to determine enterprise-Business-Context (eBC) status for employees' service requests. This is used to grant selective funding for business usage, which is distinguished from unfunded personal usage. The eBC Model interprets enterprise objectives via layered prioritization. It computes the eBC status from dynamic Attributes, grouped into Factors that characterize the Task context. We built the eBC Model with typical Task Templates and representative scenarios. The simulation results proved the eBC Model to be robust, flexible and easily customizable by non-Telecom people.
